2020 HU in 2014 BR*
I recently purchased a 2014 BRZ premium with the factory head unit and want to incorporate android auto. The car came with a 2020 BRZ Harmon Cardon HU that included AA (not installed). Other than installation and powering the amp wake up wire, is there anything I need to add or modify just to get AA working? I dont need the factory nav or other features. Just AA and sound.
